Camshaft

DESCRIPTION
The camshaft is constructed of ductile iron and is shot-peened in the #1 journal and valve lobe area for superior strength and durability. The camshaft is supported by a bushing at the #1 journal location, and is lubricated by a film of oil supplied by the crankshaft main journals. The camshaft is driven by a pressed on gear and its lateral movement is controlled by a thrust plate. The engine also uses solid "mushroom" style tappets to open and close the valves.
